I’d like to see these wackos try to “sustain life on their own” without a man being somehow involved somewhere down the line. They seem to have confused humans with whiptail lizards, which are all female. But spoiler alert, humans, as it turns out, are not whiptail lizards. I doublechecked.
Fun science fact: while parthenogenesis - a fancy multisyllabic word for “getting knocked up without first getting dicked down” - is real, no mammalian species are capable of it due to various mechanical quirks of the mammalian gene.
Mammals have this thing called “genomic imprinting”, where certain genes can only be activated if they come from a male parent
A viable mammalian embryo requires both a female and male parent to activate certain genes - IGF-2, for instance, which is a key developmental gene, and without which, no pregnancy will survive gestation.
Now, genomic imprinting can and has been bypassed, in the lab, but the results are grossly inefficient - out of 457 reconstructed mouse ova, only two live births occured. That is a birthrate of only 0.44%, practically extinction numbers.
